What should I do if my computer keeps blurry? What should I do if the computer always has a blurred

Display screen is an extremely common failure, there are many reasons, different reasons for the fault phenomenon is also different, the solution is also different. In the text mode, the screen is characterized by confusion of characters, and in the graphic mode, it usually appears as a graphic layer, and horizontal stripes are produced due to internal or external interference. The following are some thoughts and experiences that I hope can be used for your reference.

1 Displays produce horizontal streaks: there are two main reasons for this:

1) External interference, such as electric sparks or high-frequency electromagnetic interference near the use site of the display, this interference will cause the display screen of the display to produce white horizontal stripes. Solution: Avoid using the monitor in this situation;

2) Internal interference, this interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a bad contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reasons for this situation involve more professional technology, so it is best to ask a professional to repair it.

2 Improper display resolution setting causes blurred screen: When the monitor is set incorrectly in the resolution of Win95, there may be blurry screen failure when starting Windows, that is, the picture is layered, shaky, serious and even black screen of death. Solution:

Enter the setup or enter the safe mode of win95, and reset the display mode of the monitor.

3 Conflict between the display card and the Chinese system: In this case, when exiting the Chinese system, there will be a blurred screen, and there is no response to random keystrokes, similar to a crash, processing method: input at this time"mode

c080"can be resolved.

4. Poor heat dissipation effect of the main control chip of the graphics card: This will also produce the phenomenon of blurred screen failure, and the solution is to improve the heat dissipation performance of the graphics card.

5. The video memory speed is too low: When the video memory speed is too low to match the speed of the host, the screen will also be blurred, and the solution is to replace the video memory with a higher speed, or reduce the speed of the host.

6 Video memory corruption: When the video memory is damaged, there will be a phenomenon of blurred screen messy characters when the system starts, and the solution is that the video memory bar must be replaced.

Virus cause: Some viruses will also appear when the screen appears, and the solution: use antivirus software to eliminate it. Handling of special faults of the display caused by capacitor failure.

Fault phenomenon: An AOK color display fails after a period of use. After the computer is turned on, the monitor does not display, and after about 5 minutes, the monitor gradually lights up, but the right part of the screen is darker and has a horizontal black line, and then slowly turns to a normal state.

It is recommended to check the graphics card driver first, and then check the hardware (all hardware involving the display, such as wires, graphics card data cables, graphics card, and heat dissipation). It is a reinsertion of the hardware interface and cleaning up the dust at the same time.

If you don't want to do it, test your monitor on a different console to see if there's a problem with the monitor.

First, see if there is a problem with the computer system, such as poisoning or something, if the computer system is normal, try to change the graphics card driver, if it still doesn't work, see if there is a problem with the graphics card, and secondly, see if there is a problem with the monitor!

What to do if the computer monitor has a blurred screen.

1. The graphics card driver is not compatible. It is recommended to install the latest official drivers for your graphics card.

2. There may be a problem with the system or matching. Build and sell stupid "one-click restore system" or reinstall the system.

3. Restore the default value of BIOS. Check whether the memory and graphics card are incompatible or faulty (sometimes the screen is blurred when the memory is faulty).

4. The temperature of the graphics card is too high, causing virtual soldering or damage. If the temperature is too high, clean up the motherboard, graphics card, and fan. If there is a problem with the fan, replace the cooling fan. If it doesn't work, send it for repair.

5. The display connection is loose or there is a problem with the connection.

6. The cable of the screen is loose.

7. The screen is broken.
